DEF tank leak and nasty smell in sleeper

I cant think of any other occurance tht would cause it and was surprised to see the leak. Its definitely the def I saw the white flakes around the liquid and I drip some on my coat and its the same smell. It smells like a cattle truck.

I think hes worried about getting in trouble. That im not worried about. #### happens. We are on a tight schedule and dont want to be down long. We are back home in a week for home time and we can put it in the shop.

 

DEF is a really odd chemical. Its not compatible with a lot of materials. I would highly recommend not patching the tank if its leaking. Not only that but it is possible to chemically alter DEF just by introducing something as simple as dirt into the tank.

TLDR: Patching a leaking DEF tank could cause huge problems in the SCR system.

 

Good point.
I'd try to find the leak. But then again lately I am of the mind set if I want something fixed I will fix it myself. Until defeated. Then I pay.

 

If it works, it shouldn't be an issue. If it doesn't work and you get the poor quality DEF code, you're still replacing the same part to fix the problem. I don't think it would plug up the doser or pump if it's being leached at a molecular level.

 

Maybe pothole didn't cause the problem; could be coincidence.
If there's no damage from the pothole, keep the DEF tank full and write up the leak to CYA.

 

No visible damage anywhere. I didn't hear anything bottom out. I just don't know what else it could be. We saw no curb action that I know of and no debris in the road. Under the truck appears normal, but I'm not a mechanic. Theres just a dripping leak it looks like its coming from up in it. About drip every 2 seconds. Codriver says it will leak a lot more while we are driving.

 

If def is caustic why is it harmless

It's between sea water and baking soda, so...

 

That's trucking; DEF is harmless and the driver is caustic.
